Fillers Method

This method is on par with the No-Sand Method in terms of quality of finish but is a slightly slower process. However, it is faster than hand-sanding or using a Dremel to post process your prints. Relevant PPE such as a mask and gloves should be used when utilising this method.

Materials

• High-cover aerosol paint + primer (such as Rustoleum 2X)

• Acrylic or enamel fast-drying spray putty (such as Superfine High Build Filler)

• Isopropyl wipes or similar to clean parts

Method

1. Ensure that your printed parts are clean and dry, wipe the parts down with Isopropyl wipes or a similar product and let dry.
2. Begin by applying a thin coat of high-cover spray-putty to the parts. Note that the spray-putty may cause blotching to your surface if applied too thick or unevenly across your surface.
3. Wait 30-45 minutes (or as instructed on bottle) between coats.

4. Re-coat your parts a total of 3-5 times.
5. Once you have applied all the necessary coats (according to how smooth you would like the finish of your surface) leave your parts to dry overnight. The spray-putty will fill up the gaps between the prints' layers and level your surface smoothly.

6. Apply a medium coat of high-cover spray paint to your part.
7. Wait 10 minutes between applying your paint coats.

8. Repeat the painting process 3-5 times as necessary.
9. Wipe your parts clean and you are ready to go.
